To all lwhom t mfr/y bomen:

Be it known that I, THoM'As EYNoN, a citizen of the United Statesresidin at Rock Island, in the county of lock Is and and State of Illinois, have inventedcertain new and \useful Improvements in Bolt-Hopperin Machines; and I do herebyu declare the fo lowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it apf pertainsl to make and use the same.

This invention relates to mechanism for automatically feeding bolts tol a bolt assem-l blin machine, threading machine, or like mec anism for performing one or more operations upon bolts.

The object of the invention is to automatically separate single bolts from a mass,

arrange them with similar ends all pointing.

throughout the several views:

. connectin Figure ljis a side elevation of a machine embodying my invention;

Figure 2 is an end elevation thereof viewed from the right of Figure 1;`

Figure 3 is a sectional plan view taken on the line 3-3 of Figure 2, the peripheral from the plane of the inner diametrical face groove, track and belt rim being omitted for simplicity of illustration;

Figure 4 is a detail in erspective of one of the bolt separating liig ts carried on the interior of the bolt separating drum.

In the embodiment of my invention illustrated in the drawings, 43 indicates the base of a framework on which the mechanism is supported. Rising from the base 43 are four heavy standards 44, of equal length arranged in pairs, one pair rearwardof the other. Extending crosswise` of the base, the standards -of each pair, are sills 4-5.

bearing bracket being composed of two `ward 'at cach end providln y caring brackets 3 are arranged on said sills 45, one adjacent each end eachl spaced bearing members rising from a flatv base. The said bearing members are perforated to rece've shafts or axles 32 upon which are mounted cylindrical bearing rollers 22.

Resting upon and adapted to rotate on bearing rollers 22 is a cylindrical drum 1 having annular iianges 2, 2 extending ina passage entirely through, but of less dlameter than the drum. The annular flange 2 on one end of the drum is preferably made of a separate annular plate bolted td' the drum, it being shownin Flgure 1 at the rear end of the drum. This construction renders the drum capable of being easily bored or otherwise machined. In order to prevent axial movement of the drum it may be provided with an exterior annular groove 22 in which one pair of rollers 22 engage. The otherlpair of rollers 22 is shown as engaging a relief surface or track 22", the circumference of which is, however, the same asv the circumference of the bottom of the groove-22". By this arrangement of bearing surfaces on vthe drum with respect to the bearing rollers the drum may be kept from endwxse motion with a minimum of surface frictionally pressing against the rollers.

Supported on a bracket 14 rising from the rearmost sill 45 is a hoppe'I` 27 the'axis of which is inclined downward toward the drum and which is in form a segment of a cylinder. The inner end of said hopper terminates substantially in the plane of the inner diametrical face of the flange 2, so that material placed in said hopper 27 will slide by gravity; and be delivered into the 'drum between t efront and rear flanges.

Within the drum 1 extending substantially `a chute 21,- V-shaped in cross section, the

incline of which may be substantially -the same as that of the hopper 27. The said chute 21 is fixed with respect to the hopper 27, the rear end of said chute being supported above and from the hopper 27 by braces or brackets 28. That portion of the chute 2,1 that projects through the front end of the hop er is sustained by brackets 12 and 13 whlc are secured to the front side of the front sill 45 and incline upward and inward into contact with the sides of the chute 21 which may be secured to\the upper ends f. of said brackets. An open-ended, parallelsided slot 21a is formed in the projecting end of the chute.

Arranged in a pluralityv of circumferen- `tial rows about the inner periphery of the i rlhe flights are secured to the drum in such a position that the groove 42 extends parallel with the axis of rotation of the drum and the roove is placed on that side of the flight which advances during rotation of the drum.

A pair of brackets 7 is secured to the front of the forward sill 45, one on each side of a perpendicular plane inclu-ding theaxis of the drum. Extendingl between the upper ends of said brackets 7 is a rock shaft 33 supporting doubleF bearing members 9 which are adapted to oscillate on or with shaft 33 and to be adjusted thereon toward or from each other. rlhe uppefr ends of said members 9 are pierced atfright angles to the shaft 33 and receive the rear endtrunnions of a pair of rolls 31. The front ends of said rolls 31 are journaled in bearin s 10, ad-

.y justable by means of pins 1()a in t e arcuate Y slots 10b in the arms 24 which project upward from rigid bracket arms 23 stretching diagonally upward and inward from the brackets 7 secured to the front side of the forward sill 45. A spreader 29 connects the upper ends of the arms 24 together. From the construction described it will be apparent that the inclination of the rolls 31 may be changed and also that the distance apart of the inner ends of said rolls may be varied.

The discharge "ends of rolls`31 may be sepa.-4

rated more or less by substituting spacing bars 29 of suitable length, or bymaking the connections between spacing bar and bearings 10 adjustable (not shown) in anyA obvious manner. Should the adjustment of the rear ends of said rolls render it necessary the driving gears 20, by means of which one roll may be driven from the other, may be removed and gears of a diferentsize substituted. The rearmost end o'f the trunnion` of one of the rolls 31 (the right hand roll as illustrated, looking toward the frontend of the" machine) is provided with a grooved pulley wheel 19 by which the saidright hand roll may be rotated and, by engagement of the gears 20, both rolls rotated in opposite directions, the direction of rotation being ed from slippin means of the col ar 25. A suitable driving intense such that their adjacent surfaces move upward in unison.

lln order to operate the mechanism thus far described, the transmission gearing shown in the drawings may be used, although other suitable transmission, it will be clear, can Vbe substituted for it without changing the principles of my invention. A main driving pulley 17 may receive motion from a line shaft or from any desired prime mover. rl`he main driving pulley 17 is banded by belt 17a to a pulley 16'which rotates about theaxis of the stud or shaft 36 carried by the hanger 6 secured to the under side of the rear sill 45. Rotating with the pulley .16 isa cone or stepped pulley 8 held from endwisemovement on the shaft 36 by the collar 26. Carried on a stud or shaft 35 4projecting from the bearing hanger 5, supported on the upper side of the base 43 in substantially the same plane as the' hanger 6, is a` cone or stepped pulley 8 having its graduated band surfaces reversedn position with respect to those'of pulley 8, so that a belt passed around the largest step of the pulley 8 will it around the smallest step of the pulley 8a. The cone pulley 8a is preventendwise on shaft 35 by belt 8", is adapted to drive the cone pulleyyee 8 from said cone ulley 8. A gear wheel 37 is rigidlyisecuredjwith respect to the cone pulley 8a so as to rotate with it. Said gear 37 is in mesh with a larger gear 15 mounted on a rotary shaft 34 which is'journaled in bearing brackets 4 secured to the inner side faces of the left hand standards 44. Rotation of the gear 15 turns shaft'34. 0n said shaft 34, between the bearing brackets 4, is av belt pulley 11, around which and around the exterior periphery of the drum 1 is engaged a belt 11a whereby rotation of the pulley 11 rotates the drum 1. For convenience a raised belt rim 11b may be formed on or secured to the druni 1, which belt rim may be crowned if desired. Secured to the forward end of the shaft 34 is a grooved pulley 18 designed to receive a belt for driving the pulley 19, before mentionedfon the rear end of the trunnion of left-hand feed roller 31.

. By the transmission mechanism described it will be evident that gear 15 may be rotated at various speeds by properly adjusting the belt 8b with respect to the driving y and driven cone pulleys 8 and 8, respectively. 'lhe gear 15 imparts rotation to the shaft 34 from which the drinn and the feed rolls 31 are driven so that the said drum and feed rolls may be operated at various speeds as may be found desirable. I

Threaded through suitable bearinv s 38 inA the corners of the base 43 are a ju ting screws 30 havin at theiiI lower ends bearing shoes 39 a apted tothrust upon the orotherwise thrown indiscriminately into the hopper 27. Gravity will cause said bolts to slide downward vand be' discharged into the interior of the drum 1 between the annular flanges 2 and 2a. In the machine shown the drum is designed to rotate in a.

clockwise direction viewed from the rear. As the drum rotates the bolts will be tumbled about in the bottom of the drum and when `any bolt happens to fall'lengthwi'se into a pocket 42 it will be carried upward and dropped sideways 'into the chute 21. The

flight and pocket are so designed that only one bolt may be picked up by one Hight at one time. The dropped bolt will'slide sideways down into the angle formed by the sides of the chute 21, be 'heldin a longitudinal position and move endwise down the chute until the notch 21a is reached, whereupon the point of the bolt,will fall through said.

notch, the head being momentarily detained by the walls thereof and the bolt `will pass thence into the space between the rolls 31, 'point downward, being sustained by its head on the rolls with its end extending downward. Thus a row of bolts will accumulate between the rolls 31 and the motion of said rolls combined with-their inclination will eii'ect the advanceof the bolts from end to end' thereof. The bolts `Amay be discharged' from the ends of the rolls 31'V between the spaced bearings 10, the heads passing underneath the spacing bar 29. If desired a pre-` determined number of bolts may be accumulated on the rollers 31 until the mechanism to which thel bolts to be delivered is ready to receive a charge orA load of'bolts. The entire series accumulated on the .rolls 31 may then be pushed along said ,rolls and delivered to the runway or other receiving means of a bolt and nut\assembling or iinishin machine. r. f l
